Basic Electronics

A light bulb or the heating wire in your toaster are basically resistors.
But they can be used for more.
They limit power, consume excess energy or divide voltages and current.
Find out how here.

In many applications, you need resistance values
that can be adjusted continuously.
Just think of volume control, light dimmers
and speed controllers.
These are the areas of application of the potentiometer.

Capacitors can be found in a large variety of electronic circuits.
They store electrical energy and can be best compared with batteries.
Inside however, they work completely different.
Find out here which rules they follow and how to use them.

Inductors generate a magnetic field.
This property is used in relays, electric motors and loudspeakers.
But inductors are also used in resonant circuits and frequency filters.
Here you find out how and why.
